MEANS FOR REMOVING AIR AND NON-CONDENSED STEAM FROM VACUUM APIARATUS,

CONDENSERS, AND THE LIKE.

To all whom it may concern Be it known that we, EMIL Jossn and VVILHELM Gnnsncnn, citizens of the Empire of Germany, and residing at Charlotten-. burg, near Berlin, Germany, have invented certain new and useful Improvements in Means for Removing Air and Non-Con- Such ejectors have, however, a .very low efliciency, andmoreover, with a given vacuum and number of revolutions they can remove only a certain predetermined quantity of air. If this quantity increases for any reason the vacuum is reduced. It is therefore necessary to make the ejector large enough to deal with the maximum quantity of air to he removed, but this results in a waste of energy when the quantity of air is normal. I

A primary object of our invention is'to obviate this defect, and to this end we insert between the condenser and the air-pump operated by the water-ejector a'steam ejector can be so adjusted that the air present in the condenser at any time is removed with ce'rtainty.

- The accompanying drawings, forming a part of this application, illustrate diagrammaticall one embodiment of our invention, parts being broken away for clearness.

Referring to thedrawings, a designates the surface condenser or vacuum-apparatus. The cooling water required for this apparatus enters at i and. leavesat ml Thg'awater of condensation is withdrawn t-hrough the pipe is by the pump g. The air and uncondensed steam passing through the pipe I) first come to the steam ejector 0, where they obtain their first increase of pressure. In the example, the steam for operating this latter ejector is supplied by a pipe p from any suitable steam-engine or exchange of heat apparatus 7-. After the first accession of pressure the steam and gases pass into an Specification of Letters Patent. Application filed. May 27, 1912. Serial No. 700,071.

intermediate chamber cl, where a separation of the steam takes place owin to condensation, this being preferably e ected by the water pumped from the main condenser be ing sent by the pump 9 through the pipe 8 into the apparatus d. v Owing to the condensation of steam in the chamber d the water serving as the cooling medium is heated, so 7 that when 1tleaves this chamber, say through the pipe 6, its temperature is higher than when issuing from the main condenser.

It, therefore, this water of condensation is to be used again, for example, as boiler feedwater, a distinct economy is effected. The still uncondensed steam and the air which ;are separated in the chamber d from the steam just referred to, are conveyed farther by means of an ejector f, e. g. a water-jet air-pump,- operated by the cooling water of the surface condenser.

Instead of the water of condensation and. air being taken separately from the main condenser, they may be taken together direct to the steamejector and thence into the intermediate chamber, whence the water of condensation may be removedby a pump in the usual manner, while the necessary access of pressure is given to the air and uncondensed. steam by means of a water-jet airpump, as above described.
